Lessons Learned From Field Deployment of the #Hemaapp: A Non-Invasive #Hemoglobin Measurement tool by Christopher M Westgard in BJSTR
Abstract
The Hemaapp [1] is a smart phone application that measures
the hemoglobin level in your finger by using the phone’s built-in
camera and flash. The hemoglobin measurement is done noninvasively,
by placing the finger of the patient on the camera of the
phone. The light from the flash allows the camera to record the
absorption of light by the blood, while the Hemaapp application
analyzes the images to determine the level of hemoglobin. The
application was developed at the University of Washington’s
Ubiquitous Computing Laboratory. The University of Washington
team worked with the NGO, Asociacion Red Innova, to test the
innovative technology in the field. The team conducted a field
deployment in a variety of diverse settings in Peru, including two
communities in the Amazon region, an urban-slum community in
Lima, and three clinics in Lima. The following report was drafted to
reflect the lessons learned in the field.
